FTB Launcher version: Ultimate v1.1.2
Minecraft Version: 1.4.7
Java version: Version 7 Update 11
So I'm playing FTB for a while now and I have a problem in singleplayer. The game normally works for about 20 minutes and then it starts freezing until it eventually crashes (not to the MC crash log but completely).
I would be glad if somebody would help me with it.
I'm using Optifine and no texturepack.
